An attractive ski helmet is generally composed of an outer shell, a main body, an inner lining, an adjuster, a fixing device, a buckle, and a spectacle buckle. The main structure as a key part is mainly to absorb the energy during impact. Generally, the material of the main body is EPS, which is similar to the packaging foam used in usual times.
There are two main types of EPS, one is white material and the other is black material. The price of black material is more than three times the price of white material. The high-end ski helmet basically uses black material. It is worth noting that some brands will use black paint to turn white materials into "black materials."
From the protection scope of the helmet, it is generally divided into CLASS B, that is, the earmuffs are soft, and CLASS A helmets, that is, the earmuffs are hard. CLASS B helmets are mainly used in ordinary skiing, and CLASS A helmets are mainly used in competitions. Alpine skiing is faster, and CLASS A helmets are generally used, while cross-country skiing mainly uses ordinary CLASS B helmets.
In addition to ski helmets, ski goggles are also indispensable equipment in skiing. Most ski goggles use PC lenses, which has the advantages of increasing the rigid impact of the lens, reducing the weight of the lens itself, and increasing the clarity of vision. Some manufacturers use NXT for the lens material of the snow mirror. The impact force is far more than that of PC. At the same time, the weight is lighter and the definition can reach the optical effect. It is the best lens at present.
Because the white snow will reflect strong ultraviolet rays, which is very harmful to human eyes, another function of ski goggles is to filter ultraviolet rays. During skiing, due to exercise, the face will sweat and generate heat. Due to the relatively low external temperature, it is easy to produce fog inside the ski goggles. Qualified ski goggles will be treated with anti-fog coating on the inside of the lens to reduce the generation of mist and ensure the clarity of the lens. In addition, all ski goggles will have a single layer or multiple layers of sponge inside. The sponge's role is to ensure that when an object hits the ski goggles, it acts as a buffer.
When choosing ski goggles, choose the snow goggles with double lenses to check their clarity and color reproduction. Second, look at whether the snow mirror is veneered, because some European versions of the snow mirror will have a large gap, which is easy to enter the wind and produce mist. For beginners, it is more appropriate to choose a slightly lower price of the snow mirror. When the level reaches a certain level, then choose a more powerful snow mirror.
